Title
(EN) SILICA ADSORBENT FOR REMOVAL OF CHLOROPHYLL DERIVATIVES FROM TRIACYLGLYCEROL-BASED OILS
(FR) ADSORBANT À BASE DE SILICE POUR L'ÉLIMINATION DE DÉRIVÉS DE CHLOROPHYLLE À PARTIR D'HUILES À BASE DE TRIACYLGLYCÉROL
Abstract
(EN)
The present invention relates to an adsorbent for treating an oil comprising a chlorophyll derivative. In particular, the present disclosure relates to an improved silica gel adsorbent for removing impurities, including chlorophyll derivatives and/or trace metals, from an oil, in particular triacylglycerol-based oils. The adsorbent comprises a silica gel treated with an alkali earth metal oxide, such as magnesium oxide, and has a pH of about 7 or greater and a water content of about 3 wt% or greater.
(FR)
La présente invention concerne un adsorbant pour le traitement d'une huile comprenant un dérivé de chlorophylle. En particulier, la présente invention concerne un adsorbant à base de gel de silice amélioré pour éliminer des impuretés, y compris des dérivés de chlorophylle et/ou des métaux à l'état de trace, à partir d'une huile, en particulier d'huiles à base de triacylglycérol. L'adsorbant comprend un gel de silice traité avec un oxyde de métal alcalino-terreux, tel que l'oxyde de magnésium, et a un pH supérieur ou égal à 7 environ et une teneur en eau supérieure ou égale à 3 % environ.
